New man, new hair!

Kaley Cuoco is making a dramatic change in her life: she's getting rid of her lob and going with some pretty intense extensions.

The "Big Bang Theory" actress took to Instagram on Wednesday to give her 2.6 million followers a sneak peek of her new locks, via a selfie stick.

"It's very important for me to change my look after wrapping each season," she said, adding a smiley face. "I love playing Penny, but it's good for me to bring it back to Kaley."

"Last year I chopped it all off- this year I'm doing the opposite. With the extension master @faye.woods ….," she said of the image that shows her at the salon with long blond and dark extensions. Some of her hair is in hair ties in the snap.

"Stay tuned!," Kaley said, humorously adding, "Can't wait to read all the negative comments lol."

On Tuesday, the actress posted a video of her and her definitely-not-dating costar Johnny Galecki thanking fans and the crew for the just-finished season.

"Happy end of season 9," she captioned the video. "@sanctionedjohnnygalecki take a moment every show night to thank our audience. Tonight brought a tear to my eye! Thank you @a.ayers10 for captioning the moment and for catching the adorable wave from my day in the stands!! @glzdovr (he's never missed a show :)"

She also posted a snap of the crew after the final show had taped.

"That's a wrap on season 9 @bigbangtheory_cbs !!!," she wrote of the image. "Thank you to all the fans. You are why we do what we do. See you next season!!!!!!"

Now that she has a break from the show, the animal loving star can spend more time with her new man, billionaire heir and equestrian Karl Cook.

The two have been dating since March and he often turns up on her Instagram feed. In mid April she called him her "bae."

That's what happy looks like πŸ’—
